LLPG403 (LTE, 2× Wi-Fi, GNSS)

2×2 MIMO Wi-Fi, LTE, and GNSS Surface-Mount Antenna

The LLPG403 combines one LTE path, two Wi-Fi paths for 2×2 WLAN MIMO, and active GNSS in one low-profile surface-mount antenna.

  • Expands onboard Wi-Fi with two paths for compatible 2×2 MIMO.
  • Maintains dedicated LTE and GNSS connections beside the WLAN pair.
  • Consolidates four cables within one 1.25-inch-high enclosure.
  • Fits tall vehicles and compact fixed sites with restricted clearance.
  • Sealed mounting protects internal components in wet and dusty conditions.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

Wi-Fi MIMO, LTE, and GNSS. One Mount.

The LLPG403 combines a two-path Wi-Fi connection with independent LTE and GNSS feeds in one low-profile antenna for mobile and fixed multiband systems.

Higher-Capacity Wi-Fi: Two independently cabled Wi-Fi elements cover 2.4–2.5 and 4.9–6.0 GHz for compatible 2×2 WLAN MIMO equipment.

Independent LTE Connectivity: A separate cellular element covers 694–960 and 1710–3700 MHz without consuming either Wi-Fi path.

Multi-Constellation Positioning: Active GNSS accesses GPS, Galileo, GLONASS, QZSS, and BeiDou from the same installed antenna.

Four Connections, One Housing: All four paths share a 9.00 × 3.50 × 1.25-inch enclosure, reducing separate antenna units and mounting points.

Protected Surface-Mount Installation: The properly mounted stud configuration carries an IP69K rating and operates from −40 °C to +80 °C.

The LLPG403 is a practical fit when Wi-Fi MIMO is the priority and one LTE path is sufficient.

Ideal Applications

  • Advanced multiband modems
  • Tall vehicles with height restrictions
  • Fixed sites with vandalism risk

Example Model Configurations: LLPG403-3C3C3C2C-BLK-180
